What is the difference between disposed and dismissed in court of law?

If a case is dismissed means the Judge threw the case out of court. If a juror is dismissed, the juror is told to go home and another juror replaces him. The disposition is the final outcome. That is when the judge is through with the case. If it is a civil case, one side either has to pay the other side or not. If it is a criminal case, one person goes to jail or walks free. Anyway, everyone leaves the court room.
